No, that doesn't work.  I can't see the container anymore (It's simply a white background).

I'd like the MiddleContainer element to resize automatically....

i.e. If the <div> elements contained inside are 400px, or whatever height, the MiddleContainer will resize, maintaining the whitebackground, as the body background is grey, and this is what's currently being shown.

overflow: hidden; seems to have done it...

Im not sure that this is correct however?

no that will not really work as you expect it.
Your problem is the float however. It's quite a tricky thing to have a two column layout with a growing parent container.

I had the same problem once and used a table instead in the end.
This will give you all info about it:

That's the way floats work -- they'll overflow the bottom of their container if there isn't something to stop them.

Using overflow:auto or overflow:hidden to make an element contain its floated descendants does work, but can result in troublesome side effects sometimes. The PIE/Aslett approach, while requiring more code, is more robust.
